mrpt::nav::CHolonomicFullEval Class Reference

Detailed Description

Full evaluation of all possible directions within the discrete set of input directions.

These are the optional parameters of the method which can be set by means of a configuration file passed to the constructor or to CHolonomicFullEval::initialize() or directly in CHolonomicFullEval::options

# Section name can be changed via setConfigFileSectionName()
[FULL_EVAL_CONFIG]
factorWeights = 1.0 1.0 1.0 0.05 1.0
factorNormalizeOrNot = 0 0 0 0 1
// 0: Clearness in direction
// 1: Closest approach to target along straight line (Euclidean)
// 2: Distance of end collision-free point to target (Euclidean)
// 3: Hysteresis
// 4: Clearness to nearest obstacle along path
// 5: Like 2, but without being decimated if path to target is obstructed
TARGET_SLOW_APPROACHING_DISTANCE = 0.20 // Start to reduce speed when
closer than this to target [m]
TOO_CLOSE_OBSTACLE = 0.02 // Directions with collision-free
distances below this threshold are not elegible.
HYSTERESIS_SECTOR_COUNT = 5 // Range of "sectors" (directions)
for hysteresis over successive timesteps
PHASE1_FACTORS = 0 1 2 // Indices of the factors above to
be considered in phase 1
PHASE2_FACTORS = 3 4 // Indices of the factors above to
be considered in phase 2
PHASE1_THRESHOLD = 0.75 // Phase1 scores must be above this
relative range threshold [0,1] to be considered in phase 2 (Default:`0.75`)
